Based on Byte-Pair Encoding. The tokenization process is the following: - Moses preprocessing and tokenization. - Normalizing all inputs text. - The arguments `special_tokens` and the function `set_special_tokens`, can be used to add additional symbols (like "__classify__") to a vocabulary. - The argument `langs` defines a pair of languages. This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to this superclass for more information regarding those methods. Args: langs (`List[str]`, *optional*): A list of two languages to translate from and to, for instance `["en", "ru"]`. src_vocab_file (`str`, *optional*): File containing the vocabulary for the source language. tgt_vocab_file (`st`, *optional*): File containing the vocabulary for the target language. merges_file (`str`, *optional*): File containing the merges. do_lower_case (`bool`, *optional*, defaults to `False`): Whether or not to lowercase the input when tokenizing. unk_token (`str`, *optional*, defaults to `""`): The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this token instead. bos_token (`str`, *optional*, defaults to `""`): The beginning of sequence token that was used during pretraining. Can be used a sequence classifier token. When building a sequence using special tokens, this is not the token that is used for the beginning of sequence. The token used is the `cls_token`. sep_token (`str`, *optional*, defaults to `""`): The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for sequence classification or for a text and a question for question answering. It is also used as the last token of a sequence built with special tokens. pad_token (`str`, *optional*, defaults to `""`): The token used for padding, for example when batching sequences of different lengths. input_idsattention_maskc  ddl} | |_||_||_||_||_i|_i|_i|_ |rt|dk(r|\|_ |_ ntd|dt|d5} tj | |_dddt|d5} tj | }|j%Dcic]\}}|| c}}|_dddt|d5}|j)j+ddd }dddDcgc]}t-|j+dd }}t/t1|t3t||_i|_t9|td ||||||||| d | y#t$r tdwxYw#1swY$xYwcc}}w#1swYxYw#1swYxYwcc}w) NrnYou need to install sacremoses to use XLMTokenizer.
